Abstract
This paper studies iterative distributed algorithms for real-time available transfer capability (ATC) assessment in energy management systems of multiarea power systems. Since ATC calculations can be modeled as a special nonlinear optimal power-flow problem, iterative decomposition-coordination approaches based on constrained augmented Lagrangian methods can be applied. One special distributed scheme, called the auxiliary problem principle method, will be studied for distributed ATC assessment in this paper. A computation framework of this distributed algorithm is investigated. System partition with nonoverlapping and boundary sub-systems will also be studied. Simulations of several IEEE test systems will be conducted to validate the feasibility and the correctness of this distributed ATC. In addition, the real-time monitoring and reaction mechanism of this distributed algorithm will also be demonstrated by numerical experiments.
